[basis]cpio filesize limit...

Hi,
can anyone tell me what the maximum filesize that can be backed up using cpio
is ? I have seen some OSS notes that mention 2Gb, but these are from 1999, and
we have backed files bigger than that currently. When the backup gets to a file
of 6Gb it fails with the following:-

cpio: file "TEMP.DATA2 ": File size is greater than can fit in a binary cpio
header limit is 32 bits not saved

We are running on a Win/2000 platform with BRBACKUP 6.10 Patch level 58 &
version 7.5 of MKS cpio.
